How we handle expansion joint sealing in Balcombe Lane

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we will say so before sealing, and phased work keeps areas in use. If you have car park joints leaking onto vehicles below and previous reseals laid over old sealant, we can help, on cladding panel joints, car park decks and ramps and brickwork movement joints alike. Searching for sealant specialists in Balcombe Lane? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

In and around smaller places like Balcombe Lane, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

When to bring in a specialist

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. If others near Balcombe Lane need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Tell us which areas need to stay in use
  • Tell staff and tenants when we will be in

Advice

Cost factors for movement joints

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • How accessible the joints are
  • Which sealant the job calls for
  • Phasing around occupants
  • Site requirements such as inductions and permits

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

What we need to price the job

There’s no need for a formal survey. These details are enough to start:

  • The site address and postcode
  • Access details, including height
  • Asbestos survey details if the building is older
  • Your programme or deadline

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Reopen bays and walkways only after the stated cure time
  • Keep product details with the building records for the next reseal
  • Report split or peeling joint sealant early
  • Keep racking legs and heavy point loads off floor joints

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal and a look at the joints after winter catches any damage.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Sealing early protects the edges.

Work for main contractors and building owners

We work for building owners and managing agents on everything from one building to a spread of sites around Balcombe Lane. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Slabs, ramps and loading bays in Balcombe Lane

Balcombe Lane is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint. The 3 miles around Balcombe Lane take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.

Business parks such as Maidenbower Business Park (2.3 miles north of Balcombe Lane) have car parks, paved areas and long brick and panel elevations, all with movement joints. Hospitals like Crawley Hospital, 4.1 miles north-west of Balcombe Lane, have multi-storey or surface car parks whose joints carry vehicles round the clock. In a school such as Balcombe CofE Controlled Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Honest limits

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Damaged metal nosings or cover plates over a joint
  • A joint that has to be widened or re-detailed before it can work

Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly.

Joints and surfaces we work on

  • Precast concrete panel joints
  • Brickwork movement joints
  • Blockwork control joints
  • Car park decks and ramps
  • Cladding panel joints
  • Podiums and floor movement joints

Questions we’re asked in Balcombe Lane

Is a smaller place like Balcombe Lane outside your area?

No. Places such as Balcombe Lane are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is hospital work, at somewhere like Crawley Hospital, something you do?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you fit around our working hours?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Do you offer coloured sealant?

It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
